For the process involving compound A: A(s) → A(l), ΔH° = 8.8 kJ/mol, and ΔS° = 37.4 J/mol•K. What is the melting point of compound A?

Question

Quizplus · Accepted Answer

The melting point can be calculated using the equation: ΔG° = ΔH° - TΔS°. At the melting point, ΔG° = 0. Therefore, T = ΔH°/ΔS°. Substituting the given values, we get: T = (8.8 kJ/mol) / (37.4 J/mol•K) = 235 K. Converting to Celsius, we get: T = -38°C.
